ROLLER-BEARiNG.

SPECIFICATION forming part of Letters Patent No. 310,383, dated January 6, 1885.

(N 0 model.)

150 all whom it may concern.-

Be it known that we, HENRY H. CLAY and MILLARD D. PHILLEo, both of Cedar Falls, in the county of Black Hawk and State of Iowa, have invented certain new and useful Improvements in Roller-Bearings, of which the following is a full, clear, and exact description.

The special object of ourinventionis to prevent clogging at their ends of the endless carrier-rollers of harvesting-machines by straws and the like winding around the axles or.

gudgeons of the rollers and between their ends and the bars which support them, the inven tion being applicable as well to rollersin any situation exposed to clogging from these causes.

The invention consists in roller-bearings formed by ferrules fixed to the ends of the roller and projecting therefrom to revolve in grooves cut in the faces of their supporting bars, together with pins or gudgeons forming axles on which the rollers revolve, and in a cut-away construction ofthe ends of the rollersupporting bars, to provide clearancespaces between them and a carrierbelt traveling around the rollers, all as hereinafter fully described and claimed.

Refereneeis to be had to the accompanying drawings, forming part of this specification, in which similar letters of referenceindicate corresponding parts in all the figures.

Figure 1 is a perspective view showingportions of the platform and inclined endless graiucarrier belts of a harvesting-machine, and as running on rollers having my improved bearings. Fig. 2 is a plan view of the end parts of one of the rollers,with the carrier-belt broken away. Fig. 3 is a perspective viewof one end of our improved roller. Fig. 4 is a perspective view of the side bar of the carrier, as fitted to receive the roller. Fig. 5 is an end view of the roller, and Fig. 6 is an inner face view of the side bar.

It is well known that much trouble is caused while operating harvesting machinery by the clogging of the rollers over which the endless grain-earrying belts run, by straws catching in the end bearings of the rollers, which obstructions require the machine to be stopped, thus losing valuable time in order to clear the straws from the rollers, and at times the friction caused by the clogging-straws is sufficient to set fire to the machine, and any obstruction of the rollers acts always to increase the friction of the grain-carriers,which makes the machine run harder, thus increasing the labor of the draft-animals. By our invention we obviate these difficulties, as now will be described.

The letters A A indicate the side bars of the carrier-frames, and 13B are the rollers, journaled at opposite ends of the bars A A, over which rollers the endless carrier-belts 0 pass in direction of their respective arrows to convey the cut grain from the bed or platform carrier to the binding-table of the harvester. The carrier-belts C have the usual cross-slats, 0, to facilitate transfer of the grain, and the side bars, A A, are cut away at a nextthe return sides of the carrier-belts, to reduce the friction of the belts on their frames.

In the ends of the belt rollers B we fix axles or gudgeons D,which.run in holes E, made in the inner faces of the ends of the side bars, A, and on the ends of the rollers B we fix ferrules F, which are flush with the peripheries of the rollers and project some distance beyond the ends of the rollers, so as to enter grooves G, made in the faces of the side bars around the holes E, so that the ferrules loosely fit and run on or around bosses h, formed by cutting the grooves G, while the gudgeons D run in the holes E; and when the parts are assembled the ends of the rollers B may come close to the faces ofthe bosses H, and the ends of the ferrules F will come close to the bases of the grooves (land to the shoulders 9, formed by cutting the grooves with their outer halves or portions at the extremities of the side bars. I cutaway the extreme ends of the side bars around the shoulders g, to allow; the ferrules F and the peripheries of the rollers B to revolve in a place slightly beyond the ends of the side bars to provide clearancespaces, as at H, between the carrier-belts G and the ends of the side bars to prevent friction of the belts on the bars, as the belts travel around their frames. It is evident that whichever way the rollers B may be revolved in the side bars it will be quite impossible for straws and the like to work in between the ends of the rollers and the side bars, A, and the carriers will run smoothly with minimum friction and comparatively small expenditure of power.

I Although We have shown and particularly described our improved bearings as applied to the carrier-rollers of harvestinganaehines, it is obvious that the bearings may be used with rollers of other machinery in any situation to preventthein from eloggingatthe ends.

The gudgeons 1) may be fixed on the side bars and the rollers 13 revolve on them, if desired; but the construction shown and above described is preferred.

Having thus described our invention, what We claim as new, and desire to secure by Let ters Patent, is

1. In roller-bearings, the ferrule F, fitted to the ends of the roller'B and running in grooves G in the faces of their supporting-bars, sub stantially as herein set forth.

2. In roller-bearings, the ferrules F, titted to I the ends of the roller 13, and running in grooves G in the faces of the side bars, A, in COIllbi nation with the axles or gudgeons D on the roller or side bars, entering holes in the side bars or roller substantially as herein set forth.

3. As an improvement in the roller-bearings of endless carriers, ferrules F, fitted to the ends of the rollers 13, and running in grooves G, out at the faces of the roller-supporting bars A, so as to form shoulders g at the extremities of the bars, the ends of which bars are cut away beneath or inside of the peripheral line of travel of the rollers to form clearance-spaces, as at J, between the carrier-belts O and the ends of the bars A, substantially as herein set l forth.
